I have a PVR-500 which is sporadically failing to tune, and the only
way I can get it to restore itself into a working state is by
power-cycling the machine.
When I look at dmesg, I'm flooded with:
[423390.332526] ivtv1: DMA TIMEOUT 00000001 0
[423393.262527] ivtv1: DMA TIMEOUT 00000001 0

[423425.660026] ivtv1: DMA TIMEOUT 00000001 0
Looking through some of the archives, I enabled ivtv-ctrl -D584 and
now I get a bit of info of the card, followed by this repeating
section:
[423612.950535] ivtv1: ioctl: V4L2_ENC_CMD_START
[423613.282924] ivtv1 encoder MPG: VIDIOC_ENCODER_CMD cmd=0, flags=0

[423618.852528] ivtv1 encoder MPG: VIDIOC_ENCODER_CMD cmd=1, flags=0
For more detailed dmesg output: http://mythtv.pastebin.ca/1790617
I'm running Ubuntu 9.10 (server): 2.6.31-17-server #54-Ubuntu SMP Thu
Dec 10 18:06:56 UTC 2009 x86_64 GNU/Linux
The card has been fairly rock solid for several years, but it seems
over the past week or so (following an apt-get update/apt-get
dist-update) that it frequently becomes unusable after a few
hours/days.
Any ideas on what to do or how to troubleshoot?
Thanks!
Matt
